Abstract

The Asian clam (Corbicula javanica) is a benthic filter-feeding bivalve widely found in Indonesian waters, playing an important role both as a food source and as a bioindicator of aquatic environmental quality due to its ability to accumulate minerals and heavy metals. Despite its ecological and socio-economic importance, scientific data on its nutritional composition in Indonesia remain limited. This study aimed to analyze the proximate composition of C. javanica collected from Gege Waters, Waihali Village, East Flores Regency, to provide baseline information on its nutritional value and ecological relevance. Sampling was conducted purposively in July 2025, and proximate analysis was performed in the laboratory following standardized methods: moisture by gravimetry, ash by incineration, protein by Kjeldahl, fat by Soxhlet extraction, and carbohydrate by difference. The results showed that C. javanica contained high moisture (83.13%), protein (51.27%), ash (12.56%), moderate carbohydrate (28.05%), and low fat (8.13%). These findings confirm its potential as a high-quality protein and mineral source while emphasizing its ecological role as a bioindicator species. In conclusion, this research fills the knowledge gap on the nutritional profile of C. javanica in Indonesian waters, supports its safe utilization for food security, and strengthens its application in sustainable fisheries and environmental monitoring.

Abstract

Kawaliwu waters are one of the areas with high potential for mangrove crabs. This study aimed to examine the antioxidant potential of mangrove crabs (Scylla serrata) collected from Kawaliwu waters in Sinar Hading Village, Lewolema District. This research method was experimental and employed a quantitative descriptive approach. Mangrove crab samples were prepared, dried, and extracted using 70% ethanol using the maceration method. The antioxidant activity of the extracts was tested using the DPPH (1,1-diphenyl-2-picrylhydrazyl) method. The results showed that antioxidant activity increased with increasing extract concentration. The IC₅₀ (Inhibition Concentration 50%) value of the mangrove crab extract was 65.25 ppm, which is categorized as a strong antioxidant. This finding indicates that mangrove crabs possess bioactive compounds with potential as a source of natural antioxidants.
